Explanation:
Services are types of traffic for which protocol standards exist. Each service has a transport protocol and destination port number(s) associated with it, such as TCP/port 21 for FTP and TCP/port 23 for Telnet. When you create a policy, you must specify a service for it. You can select one of the predefined services from the service book, or a custom service or service group that you created. You can see which service you can use in a policy by viewing the Service drop-down List on the Policy Configuration page (WebUI), or by using theget servicecommand (CLI). The only option you can change of a predefined service is the service timeout.
